Thank you to everyone who joined our latest DemoFriday with Citrix as our presenters showed the advantages of using Cisco ACI and Citrix NetScaler for Layer 2-3 services and Layer 4-7 services, respectively. The automating load balancing demonstration highlighted the great strides software-defined networking (SDN) has made in a short time, and asked us to reevaluate if, as an industry, we’re still on the same page we were when the term “SDN” was first coined.
Presenters Steve Shah and Chiara Regale also addressed questions about the flexibility and malleability of the network, as well as shared scale-out features we only used to imagine. If you were in attendance, you also learned about the progress of service integration and automation, how DevOps-expertise can manage infrastructure, and automating load balancing.
After the presentation, Steve and Chiara were kind enough to take some questions from our attendees. Below, you can read Citrix’s Q&A, as well as learn more about Cisco ACI and Citrix NetScaler. Here, you’ll also find other helpful resources like the full presentation and demo-only portion of the event.
Does ACI only work in Nexus 9000 series?
Cisco: You need Nexus 9000 to enable ACI, however we offer backward compatibility between an ACI deployment and existing Nexus networks.
Does ACI provide a programmable interface where a customer can run their own application?
Cisco: Absolutely. ACI provides Northbound and Southbound programmable interfaces to allow customers to create/define their own applications. These open interfaces also allow 3rd party vendors to integrate their solutions with ACI Application Network Policies. Please refer to www.cisco.com/go/aci for further details.
Is ACI integrated with OpenStack?
Cisco: We are working with OpenStack to extend ACI policy to the Neutron plugin. A Cisco sales rep can provide you with an update on what we do with OpenStack.
Can you manage the Nexus 9000 through its CLI and the APIC through its API/CLI at the same time?
Cisco: If you are running the N9K in ACI mode, you need to use APIC (CLI, GUI or API) to configure the N9K fabric. This will allow you to maintain a consistent definition of applications across the ACI elements. However, you can connect to the individual N9K nodes to monitor and “pull information out.”
Where can we find the Citrix device package?
Citrix: Device Package: http://blogs.citrix.com/2014/05/19/citrix-netscaler-and-cisco-aci-a-look-under-the-hood/
Release Notes: https://www.citrix.com/content/dam/citrix/en_us/documents/downloads/netscaler-adc/NetScaler_ADCs_in_Cisco_ACI-Release_Notes.html
How does this compare to NetScaler and Cisco RISE solution?
Does Cisco support OpenFlow?
What protocols does ACI use for tenant isolation?
Cisco: We are a VXLAN overlay that guarantees secure multi-tenancy. You can find more details on whitepapers posted on: http://www.cisco.com/c/en/us/solutions/data-center-virtualization/application-centric-infrastructure/white-paper-listing.html
Is VXLAN overlay encap/decap H/W accelerated?
Citrix: Yes. HW acceleration allows best performance, scale and application policy tagging for visibility and telemetry.
